Configuration

Default

message:
  cancel:
    player: You are not allowed to travel through portals!
    console: '{PLAYERNAME} tried to use a portal!'
  portal:
    player: You have entered a portal and have been teleported to a different world!
    admin: '{PLAYERNAME} has entered a portal and has been teleported to a different
      world!'

How to edit

All {PLAYERNAME} will be replaced with the player's name.
To edit open the config.yml file in a text editor like Notepad Plus Plus and replace the preset messages with the ones you want to use.

If you need the default configuration back, just delete the PortalAlert folder then restart the server and it will be re-created.
